The ultra wide-angle, rectilinear manual focus lens designed for DSLR cameras.
Providing a focal length of 15mm, this lens is ideal for outdoor and indoor photography.
The new special features such as focus lock, infinity click and hyperfocal scale set a new level of manual focus lens functionality. Thanks to sophisticated optical construction and special neutrino coating, colour aberration, ghosting and flare effects have been reduced to the absolute minimum. With a minimum focusing distance of 0.28 metre (0.92 ft) and 9 rounded shaped aperture blades, the lens stands for supremely smooth out-of-focus areas. The design of the lens allows the use of 95 mm screw-in filters at the front and square gelatin filters at the back of the lens.
Firefly is the standard version equipped with three rubber seals that protect camera mount and focusing mechanism against dust, moisture and accidental water splashes. Ergonomic focusing ring with rubber grip offers the freedom to operate with the camera. It is the most lightweight lens in its class.
